Abstract:
A prefuel composition which can be used as a fuel and which is easily mixed with water and when mixed with water and petroleum oil is an excellent fuel. A method for making such a prefuel composition which includes the steps of forming a non-homogenous mixture of carbon, water and petroleum oil and heating said mixture for a period of time and separating the resulting liquid from the solid in the mixture and burning said liquid in the presence of air for a period of time and then removing the source of air to extinguish the flame. There is also described a fuel composition which includes a solution of the preferred composition, water and petroleum oil.

Abstract:
A mixed fuel of sludge and coal is disclosed. The sludge from industrial wastewater or urban sewage in sewage treatment plants, clearing up urban discharging tube system, river, lake, channel is as raw material. Thereinto, the weight ratio of sludge and coal is that sludge is 50-65% and coal is 35-50%. The mixed fuel of sludge and coal with coal as fuel of boiler are fed to the boiler respectively when using the mixed fuel. The ratio of quantity of mixed fuel of sludge and coal to the general quantity of coal for boiler is 20-30%.
Abstract:
The invention concerns fuel compositions in the form of homogenous water-in-oil emulsions and/or organic compounds, derived from heterogeneous greasy waste and containing suspended solid particles prepared by carrying out a dynamic homogenising operation and an emulsifying operation in the presence of an emulsifier and/or a base such as an alkaline or alkaline-earth metal hydroxide. Said fuel compositions can be used as fuel in various types of stokers.
Abstract:
A mixed fuel of coal dust or the like and heavy fuel oil suited as fuel for boilers, various furnaces, and internal combustion engines, is produced by adding to heavy fuel oil a dilute aqueous solution of a water-soluble high molecular compound and carbonaceous solid fuel powder such as coal dust to disperse the coal dust or the like and water (as fine particles) in the heavy fuel oil.
Abstract:
Dispersion containing water, pulverized coal and additives, which is stable for storage, pumpable and combustible by conventional technique applied for liquid fuels. The coal content amounts to at least 55 % by weight. The dispersion contains as an additive a ionic surfactant polymer with at least one hydrophobic part with great affinity to the coal surface and at least one hydrophilic part based on ethylene oxide with the mole weight exceeding 1,000. The charge of the polymer is preferably zwitterionic or cationic.

Abstract:
The present invention discloses a gasoline efficacy promoter (GEP) boosting combustion efficiency of gasoline in internal combustion engines by a mechanism of micro-dissociation comprising a microemulsion of modified bio-carbon, a surfactant, water, a modified vegetable oil and a dispersant, and a method of making it. The gasoline efficacy promoter, environmentally friendly and stable for longer than six months, can increase the combustion efficiency by more than 10%, and reduce 80% of NOx formation in exhaust emission when an appropriate dosage is added to a fuel tank in a vehicle.
Abstract:
The disclosed embodiments relate to systems and methods for heating a slurry to increase a solids concentration of the slurry while maintaining the viscosity of the slurry below a threshold viscosity. For example, in one embodiment, a system includes a fuel slurry preparation system having a slurry tank configured to hold a fuel slurry, the fuel slurry having a solid fuel and a liquid.
